The Océanic logo is an ocean liner with a set of teeth on the bow, jutting out of waves creating both a profile that suggests both a striking shark and a fleur-de-lis. The team colours are royal blue, navy blue and white, and their home arena is the Colisée de Rimouski. The team's sweater has proven popular in the United States, as Reebok has issued it with current Pittsburgh Penguins star Sidney Crosby's number 87 on it.

In 2005, the Océanic set a QMJHL record after going 28 consecutive games without a loss. The team then went on to win seven games in a row in the playoffs, improving the unbeaten streak to an unofficial 35-straight. They won their second QMJHL championship in five years and subsequently represented the QMJHL in the 2005 Memorial Cup. After losing the opener against the hometown London Knights, the Océanic beat both the defending Memorial Cup champion Kelowna Rockets, who were in their third-straight Memorial Cup, and the Ottawa 67's. Rimouski then beat the 67's again in the semi-finals to set up a rematch of their opening game against the Knights. However, the Océanic were shut out in the final game 4–0.

The QMJHL announced on April 3, 2008, that the Océanic were chosen to host the 2009 Memorial Cup.[1]

In the 2014–15 season, the Océanic captured the QMJHL championship in double overtime of the seventh game against the Quebec Remparts. Because the Remparts were the hosts of 2015 Memorial Cup, they had already qualified for the Memorial Cup tournament prior to the QMJHL final, thus entering Rimouski into the Cup tournament. The Océanic finished 1–2 in the round robin portion in the tournament, advancing to the tie-breaker to play the Remparts, ultimately losing 5–2.
